The man whose bosom neither riches nor luxury nor grandeur can render happy may, with a book in his hand, forget all his torments under the friendly shade of every tree; and experience pleasures as infinite as they are varied, as pure as they are lasting, as lively as they are unfading, and as compatible with every public duty as they are contributory to private happiness.
Johann Georg Ritter von ZimmermannLaugh as loud as you please at your companion's wit; do not even smile at his folly.
Johann Georg Ritter von ZimmermannWhen soured by disappointment we must endeavor to pursue some fixed and pleasing course of study, that there may be no blank leaf in our book of life. Painful and disagreeable ideas vanish from the mind that can fix its attention upon any subject.
